IPC: H02H3/16
Filed: 1998-11-18
Abstract: PROBLEM TO BE SOLVED: To estimate the fault section when power failure occurs due to the actuation of the DC ground detecting relay of a substation. SOLUTION: Pointer retaining voltmeters VM1-VM3 are respectively connected in parallel with DC ground detecting relays 64P1-64P3 of substations A1-A3. When a ground fault occurs in a feeder line 1, electric currents Ig1-Ig3 respectively flow to the relays 64P1-64P3. If the resistances of the circuits of the currents Ig1-Ig3 are respectively lefined as r+(L1+L3)R+R0, r+L3.R+R0, and r+(L2-L3) R+R0 (where, r, R, and R0 respectively represents resistance of a fault section, resistance of the ground and feeder like 1 per km, and internal resistances of the relays 64P and L1, L2, and L3 respectively represents the distances between the substations A1 and A2, between the substations A2 and A3, and between the substation A2 and the fault section).  When the distances L are long, the both-terminal voltages V of the internal resistors of the relays 64P become smaller by roughly inverse proportion to the distances from the fault section. Therefore, the fault section can be discriminated roughly.

Title: Labeling device
Inventor: OYAMA KATSUMI
IPC: B65C9/26
Filed: 1993-12-24
Abstract: PURPOSE:To obtain a maintenace-free labeling device which retains its performance for a long period, by pressing a label and holding it to a peeling-off base of labels, interlocking with a carrying means and also providing a pressing member to correct the posture of the label. CONSTITUTION:A part of label 12 is separated from a paste board 11 due to an acute curvature by the use of a peeling-off base 20 for labels and protruded from the front end 21 of the peeling-off base 20. A suction pad 30 is transferred to the position where it holds the peeled-off label by a transfer means. When the label 12 is carried by the suction pad 30, the label is pressed by a pressing face 42 through a contact member 50 of label with a pressing member 40 interlocking with the suction pad and held on the peeling-off base 20. In this way, the posture of label is corrected to become almost parallel with the carrying face 31 of the suction pad 30. Since the pressing member 40 gets into contact with the label 12 only when the suction pad carries the label, the abrasion of the pressing member 40 hardly generates and hence, an excellent durability can be obtained.
